Abstract: A method includes using rules included in two or more preflight profiles to apply to a document. The preflight profiles may be selected to reduce possibilities of conflicts. The preflight profiles may be selected based on global settings or local settings. The preflight profiles may also be selected based on priority. When there are conflicts, conflict resolution techniques may be applied.

Abstract: A gastric band assembly has one or more bladders incorporated therein to minimize or modulate changes in intra-band pressure in response to changes in stoma area and band stoma area. The balloon portion of the gastric band encircles stomach tissue thereby forming a band stoma area. With the bladders incorporated in the gastric band assembly, the affect that changes in band stoma area have on intra-band pressure are minimized so that the patient stays at or near the physician set intra-band pressure longer than with a gastric band alone.

Abstract: A bladder assembly is provided in order to maintain the pressure in the balloon portion of a gastric band in a range corresponding to a so-called Green Zone. Multiple bladders are connected by flexible tubing which is connected at a distal end to the balloon portion of a gastric band. The elastically expandable bladders provide fluid pressure on the balloon portion of the gastric band in order to maintain the intra-luminal pressure within a desired range over a prescribed fill volume. A flow restrictor is positioned between the balloon portion and the bladders to restrict fluid flow from the balloon to the bladders during patient swallowing.

Abstract: A system that converts color coefficients between color spaces. During operation, the system receives a color profile comprising a lookup table which defines a conversion of color coefficients between a source color space and a destination color space, wherein the source color space includes a black color channel. Next, the system identifies a darkest output color value in the destination color space produced by the color profile, and also identifies entries in the lookup table corresponding to a maximum possible value for the black color channel of the source color space. The system then updates the identified entries with an achromatic equivalent of the identified darkest output color value, whereby source colors having the maximum possible value for the black color channel are mapped to the achromatic equivalent of the identified darkest output color value.

Abstract: This specification describes technologies relating to directional feathering of an image object. In general, one aspect of the subject matter described in this specification can be embodied in a method that includes obtaining an image object and directional information for the image object, the object including a shape having edges. The method also includes creating an opacity mask for the image object based on the shape of the image object. The method further includes processing the opacity mask such that opacity values in the opacity mask are different going from edge to interior of the shape and the opacity mask is processed in accordance with the directional information of the image object. Additionally, the method includes outputting a composite image based on the image object and the opacity mask.

Abstract: A system that selectively converts color values for objects within a document based on color profiles, wherein a color profile defines a conversion for color values between a source color space and a destination color space. During operation, the system determines whether an object-level color profile exists for an object in a document. If so, the system determines whether an object-level flag for the object is set to honor the object-level color profile. If so, the system uses the object-level color profile and an output color profile to convert color values for the object in the document.

Abstract: A lead anchor includes a body with opposing first and second major surfaces and at least one edge surface between the first and second major surfaces. The body defines a first channel, a second channel, and a notch. The first channel extends from the edge surface of the body and is open at the first major surface. The second channel extends from the edge surface of the body and is open at the second major surface. The notch extends from the edge surface of the body, defines an opening from the first major surface through the body to the second major surface, and intersects the first channel and the second channel. The first channel, the second channel, and a portion of the notch define a passage through the body so that a lead can be inserted into the notch and turned to dispose a portion of the lead within the passage. The lead anchor can be part of a kit or system that also includes a lead.

Abstract: A vertically and horizontally adjustable chair armrest is disclosed. The armrest includes an outer shroud, an upstanding support with a central opening and an armrest base. Within the central opening is a guide tube that moves vertically and has oppositely disposed slots. Within the guide tube, but mounted to rotate only, is a rod. At the lower end of the rod is a locking element that extends through the slots in the guide tube. The rod is rotated by a user pivoted lever bearing down on a spring biased activator nut. The nut is keyed to move only in a linear direction but is threaded to engage a mating thread on the rod, thereby causing the rod to rotate. When the locking element is rotated out of engagement with notches in the support opening, the armrest may be adjusted in a vertical direction. Releasing the lever allows the spring to bias the locking element into engagement with the notches to lock the armrest.

Abstract: A chair back is disclosed and includes a mesh material connected to a two-piece carrier, the carrier being deformable and stretchable. The carrier has a bottom edge including a groove and is engageable by tabs attached to a transverse member of a chair frame assembly. The upper ends of the carrier each includes an opening for receiving a spherical end portion of the upper end of the chair frame assembly. Engagement of the carrier with the chair frame assembly is accomplished by stretching the carrier and mesh between the transverse member and the spherical end portions. The chair back includes a lumbar support which is mounted to slide along the side edges of the carrier and along vertical supports of the chair frame assembly, the lumbar support causing the chair to tension forwardly. The chair back is pivotal under the influence of a chair user and is pivotally connected to the chair seat so as to cause the chair seat to also pivot in response.

Abstract: A height and pivot-adjustable office chair arm assembly with an arm rest that can be raised to different vertical positions by actuation of a gas cylinder and having a shroud surrounding and vertically movable with respect to at least a portion of an arm support that is hollow and surrounds the gas cylinder such that the shroud is vertically movable in relation to at least a portion of the arm support. The shroud is connected to the gas cylinder at an upper end for vertical movement by the gas cylinder. An arm rest pivot support is attached only to the shroud and receives the arm rest assembly and enables the arm rest assembly to pivot in a horizontal plane thereby allowing the arm rest assembly to assume any selected rotational position.

Abstract: A locking device for allowing horizontal seat positioning of a chair seat has a friction strip or brake pad between a seat pan and a seat plate. A screw and spring assembly is used to resiliently hold the seat pan and the seat plate together such that by lifting up on the forward portion of the seat pan, the friction strip, if attached to the seat plate, is separated from the seat pan allowing the seat pan to be moved horizontally in forwardly and rearwardly directions, thus adjusting the seat position. When the front of the seat pan is lifted substantially vertically, the screw and spring assembly is compressed to allow the seat pan to separate sufficiently from the friction strip and allow relative movement of the seat pan with respect to the seat plate. As an alternative, a lever may be used to loosen a locking mechanism and therby allow seat adjustment.

Abstract: A body support system is provided having improved static and dynamic mechanical response characteristics and improved thermal regulation, and which can provide energy dissipation capabilities. The body support system can be of a modular construction to provide mechanical response characteristics suited to a particular user or group of users, or to a particular environment of use. The energy dissipation characteristics are provided by a flexible fluid compartment containing a volume of viscous fluid, such that at least a portion of the fluid moves within the compartment in response to a vertical force on the compartment.

Abstract: An ergonomic chair includes a four-bar linkage arrangement wherein a lower frame member is provided with a rigid front support and a rigid rear support with a seat member pivotably connected to the front support. A back rest has an upper support pivotably connected at an upper end of the rear support of the lower frame member. A link member pivotably connects at a first end to a rear support of the seat member and at second end to a lower support of the back rest. This novel arrangement permits tilting movement of the backrest rearwardly relative to the lower frame member causing elevation of a rear portion of the seat member, permitting the feet to remain on the floor and alleviating pressure on the user's thighs, while rotation occurs closely coincident with the pivot axis of the user's hips and while maintaining a generally uniform gaze line.

Abstract: An adjustable chair seat with a locking mechanism is disclosed. The chair includes a seat pan, a seat plate and a torque limiting fastener. The seat pan and seat plate have openings for receiving the fastener which comprises a cup handle and a threaded insert. The threaded insert is engaged with the seat pan through an opening in the seat pan while the seat plate is sandwiched between the seat pan and the fastener. Once engagement is made, the fastener cannot be disengaged; and once a predetermined resistance is reached the cup handle slips relative to the threaded insert so as to cease the application of torque to the threaded insert.
